Construction and operating principle
A metered oil chamber dissipates energy while the nitrogen chamber provides the return force. Application-specific metering is selected from the required response.
Applications and selection
Cranes, rail equipment and heavy production machinery. Provide mass, impact speed, drive force and available stroke for application review.
Catalog operating conditions
- Series catalog temperature, standard configuration
- -10 … 60 °C
- Series catalog temperature, optional fluid and seals
- -35 … 100 °C
Temperature ranges are series catalog references. Confirm the fluid, seals and ordered configuration; an optional range is not a standard-model rating.
Return force is separate from allowable impact force and drive thrust. BA denotes the optional bladder accumulator; do not assume it is fitted.
